The superblock could not be read or does not describe a correct ext2filesystem. If the device is valid and it really contains an ext2filesystem (and not swap or ufs or something else), then the superblockis corrupt, and you might try running e2fsck with an alternate superblock: e2fsck -b 8193 <device>

try to reassemble after you fix the superblock on sdb. you may not have to do all the disks. if that does not work then fix the superblocks on c and e and then try the reassemble command. it will work eventually.

Sorry to be a pain in the you know where..........I have tried a number of the superblocks and I am getting the same error as per below and I tried e3fsck and that didn't work either as it came back as command not found
